Middlesex opening batsman Chris Rogers says the team must improve their performances to finish the County Championship season strongly.
The side have not won any of their last five games in Division One.
Rogers told BBC London 94.9: "We've lost that rhythm we had just before the Twenty20 competition but that's what happens in a season.
"We have to start playing better again. We aren't playing too badly but need to fight back."
Middlesex, who won the Division Two title last season, currently sit fifth in the top flight
"There's no shame in that," Rogers continued. "There are some excellent sides in this competition.
"We've got four games to go and every side is good, so we've got a real challenge ahead of us to make sure we finish well."
